is H or halogen atom. The preparation method of the derivatives and the use thereof in manufacture of organic thin film field effect transistor or organic solar batteries are also disclosed.
Metal values are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by pyridine derivatives containing the substituent --(COX).sub.A where X is the group --OR.sub.1 or --NR.sub.2 R.sub.3 and n is 1, 2 or 3. R.sub.1 is a hydrocarbyl group containing from 5 to 36 carbon atoms and R.sub.2 and R.sub.3 are hydrogen or a hydrocarbyl group wherein R.sub.2 and R.sub.3 together contain from 5 to 36 carbon atoms. The process is especially useful for the recovery of metals from leach solutions derived from sulphur-containing ores such as chalcopyrite.
